Dibenzyl sulfoxide is commonly used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals. It plays a role in the synthesis of various active pharmaceutical ingredients (APIs) due to its ability to act as a sulfoxide donor or participate in oxidation reactions. Additionally, it is utilized in research and development for studying reaction mechanisms and developing new synthetic pathways. Its application extends to the field of material science, where it is sometimes employed in the preparation of specialized polymers or coatings. In industrial settings, it may also be used as a solvent or additive in specific chemical processes.
